Description

Technical Field

[0001] The present application relates to the technical field of cooking devices, and in particular to a cooking device control method and a cooking device. Background Art

[0002] With the development of science and technology, cooking devices have entered thousands of households. The use of cooking devices is very convenient. However, when cleaning the cooking devices, most of them are done manually. On the one hand, this cleaning method has poor cleaning rate and efficiency. On the other hand, it requires manual cleaning, which greatly reduces the user experience.

[0003] Therefore, how to automatically and efficiently clean the cooking device is a problem that urgently needs to be solved. Summary of the Invention

[0004] The present application aims to solve the technical problem of how to automatically and efficiently clean a cooking device.

[0005] In a first aspect, an embodiment of the present application provides a control method for a cooking device, the cooking device comprising: an inner pot, the inner portion of the inner pot forming a heating cavity, the heating cavity being used to hold food; a body forming an outer shell of the cooking device and providing an installation space for the inner pot; a door rotatably connected to the body and used to open or close the inner pot; a heating device disposed in the body and used to heat food; a cleaning device disposed in the body and used to clean the heating cavity; and a turbidity sensing device disposed in the body and used to sense a contamination level of liquid after cleaning the heating cavity.

[0006] The control method includes: controlling the cleaning device to perform test cleaning on the cleaning area in the heating chamber, determining the regional dirtiness value of the cleaning area through the turbidity sensing device; determining a cleaning mode for the cleaning area according to the regional dirtiness value of the cleaning area; and performing formal cleaning on the cleaning area according to the cleaning mode of the cleaning area.

[0007] In an embodiment of the present application, a test cleaning of the cooking device is first performed, and the contamination value of the wastewater generated during the cleaning is obtained. The contamination value of the wastewater reflects the degree of contamination of the cleaning area in the cooking device. Therefore, the present application then determines a cleaning mode for the cleaning area in the heating chamber based on the contamination value of the wastewater. The cleaning mode includes cleaning time and cleaning intensity. The larger the contamination value, the longer the cleaning time and cleaning intensity. Finally, based on the determined cleaning mode, the cleaning area in the heating chamber is formally cleaned. This achieves the technical effect of automatically adapting the cleaning mode based on the degree of contamination of the heating chamber, achieving optimal cleaning efficiency and cleaning effect.

[0008] In one embodiment of the present application, the cleaning device is controlled to perform test cleaning on the cleaning area in the heating chamber. Before determining the regional dirtiness value of the cleaning area through the turbidity sensing device, the method further includes: when it is sensed that the door body is closed, responding to the user's instruction information to enter the cleaning mode; monitoring whether the heating chamber meets the cleaning conditions, if the heating chamber meets the cleaning conditions, controlling the heating device to start heating the heating chamber, so that the heating chamber is heated at a constant temperature of the preheating temperature; if the heating chamber does not meet the cleaning conditions, prompting the user that the heating chamber does not meet the cleaning conditions.

[0009] In this embodiment, the cleaning of the heating chamber requires that the interior of the chamber meet cleaning conditions. For example, if certain components within the chamber need to be moved to a predetermined position, and if food or other objects to be heated are still present within the chamber, these factors can affect the spraying of liquid by the cleaning device and the cleaning effect. Therefore, when the cooking device responds to user instructions and enters cleaning mode, it first monitors whether the chamber meets the cleaning conditions. Only when these conditions are met does it begin heating the chamber. If the chamber does not meet the cleaning conditions, the user is prompted to inspect and clean the chamber to prevent safety incidents and reduce cleaning effectiveness. Heating also softens stains, facilitating cleaning of the chamber.

[0010] In one embodiment of the present application, the turbidity sensing device includes a light source and a photosensitive device. Determining the regional dirtiness value of the cleaning area by the turbidity sensing device includes: causing the light source to emit a light beam, the light beam irradiating sewage and being sensed by the photosensitive device, the sewage being generated by test cleaning of the cleaning area; determining the dirtiness value of the sewage based on the brightness of the light beam sensed by the photosensitive device; and determining the regional dirtiness value of the cleaning area based on the dirtiness value of the sewage.

[0011] In an embodiment of the present application, the turbidity sensing device includes a light source and a photosensitive device. The light source emits a light beam that passes through the sewage and is sensed by the photosensitive device. If the photosensitive device senses a relatively high brightness of the light beam, it indicates that the light beam has passed through the sewage without undergoing many reflections before being sensed by the photosensitive device. In other words, the sewage is relatively clean and does not contain many impurities, and the sewage turbidity value is relatively low. If the photosensitive device senses a relatively low brightness of the light beam, it indicates that the light beam has undergone many reflections in the light path before being sensed by the photosensitive device. In other words, the sewage contains a large number of solid shell particles and impurities, and the sewage turbidity value is relatively high.

[0012] The brightness of the light beam sensed by the photosensitive device is inversely proportional to the sewage pollution level. This method is relatively accurate and simple to obtain the sewage pollution level, greatly reducing the difficulty of determining the sewage pollution level and improving the efficiency of determining the sewage pollution level.

[0013] In one embodiment of the present application, the cleaning device is controlled to perform test cleaning on the cleaning area in the heating chamber, and the regional dirtiness value of the cleaning area is determined by the turbidity sensing device, including: performing test cleaning on each cleaning area located on the inner wall of the heating chamber to obtain the dirtiness value of the sewage generated by each cleaning area; and determining the regional dirtiness value of each cleaning area according to the dirtiness value of the sewage generated by each cleaning area.

[0014] In the embodiment of the present application, each cleaning area located on the inner wall of the heating chamber is tested and cleaned separately to determine the regional dirtiness value of each area. In this way, the corresponding cleaning mode is determined based on the different dirtiness levels of each cleaning area, achieving more efficient cleaning and a higher degree of cleanliness.

[0015] In one embodiment of the present application, the regional pollution value of each cleaning area is determined based on the pollution value of the sewage generated in each cleaning area, including: obtaining the pollution value of the sewage generated in the cleaning area through the turbidity sensing device at each set time interval until the number of acquisitions reaches a set number; and taking the average of all pollution values ​​of each cleaning area as the regional pollution value corresponding to each cleaning area.

[0016] In this embodiment of the present application, during the test cleaning process, the initial contamination value of the wastewater generated by the test cleaning is obtained at set intervals until the number of acquisitions reaches the set number. In this way, each cleaning area corresponds to multiple initial contamination values, and the average of all corresponding initial contamination values ​​for each cleaning area is taken as the contamination value. This makes the regional contamination value obtained for each cleaning area more accurate and representative.

[0017] In one embodiment of the present application, before the test cleaning is performed on each cleaning area located on the inner wall of the heating chamber to obtain the dirtiness value of the sewage generated in each cleaning area, the method also includes: dividing the area to be cleaned located on the inner wall of the heating chamber into several cleaning areas according to the user's instruction information.

[0018] In an embodiment of the present application, based on the user's instruction information, the area to be cleaned on the inner wall of the heating chamber is divided into several cleaning areas, so that these divided cleaning areas can be cleaned in different cleaning modes. This can be carried out according to the degree of dirtiness of the area to be cleaned on the inner wall of the heating chamber. The different degrees of dirtiness of different parts of the inner wall of the heating chamber are fully considered. Areas with similar degrees of dirtiness can be divided into the same cleaning area and cleaned in the same cleaning mode. This avoids the situation of incomplete cleaning or waste of resources. Because if all areas with different degrees of dirtiness are cleaned uniformly, if you want to clean them completely, you need to use the area with the most serious dirtiness as a reference for cleaning. This is completely unnecessary for areas with less serious dirtiness and will waste resources. If you want to save resources, you use areas with general dirtiness as a reference for cleaning, which will result in incomplete cleaning of areas with serious dirtiness. Therefore, the present application divides the area to be cleaned into cleaning areas with different degrees of dirtiness, which not only improves cleaning efficiency but also saves resources.

[0019] In one embodiment of the present application, determining the cleaning mode of the cleaning area according to the regional dirtiness value of the cleaning area includes: determining the cleaning time and cleaning intensity of each cleaning area according to the regional dirtiness value of each cleaning area.

[0020] In the embodiment of the present application, the cleaning time and cleaning intensity applicable to each cleaning area are matched according to the regional dirtiness value of each cleaning area, which ensures that each cleaning area can be cleaned thoroughly without wasting cleaning resources.

[0021] In one embodiment of the present application, determining the cleaning mode of the cleaning area based on the regional dirtiness value of the cleaning area also includes: if the total cleaning time is determined and each of the cleaning areas is cleaned in sequence, determining the cleaning time of each cleaning area based on the proportion of the dirtiness value of each cleaning area in the sum of the regional dirtiness values ​​of all cleaning areas; determining the cleaning intensity based on the ratio of the regional dirtiness value of each cleaning area to the corresponding cleaning time.

[0022] In an embodiment of the present application, when the total cleaning time is fixed and each cleaning area is cleaned sequentially, the sum of the regional dirtiness values ​​of all cleaning areas is first calculated, and then the amount of cleaning time that can be allocated to each cleaning area is determined based on the proportion of each cleaning area in the sum of the regional dirtiness values ​​of all cleaning areas. Finally, the cleaning intensity is determined based on the ratio of the regional dirtiness value to the cleaning time. The larger the ratio, the shorter the cleaning time is compared to the regional dirtiness value of the cleaning area, and a higher cleaning intensity is required to clean the cleaning area. This ensures that the cleaning effect of each cleaning area can be guaranteed as much as possible regardless of the length of the cleaning time, and secondly, it saves cleaning resources.

[0023] In one embodiment of the present application, after the cleaning area is formally cleaned according to the cleaning mode of the cleaning area, the method further includes: generating a historical cleaning pattern according to the distribution of each cleaning area in the heating chamber, and the cleaning time and cleaning intensity corresponding to each cleaning area.

[0024] In this embodiment, a historical cleaning pattern is generated by recording the distribution of previously cleaned areas, as well as the cleaning time and intensity for each cleaning area. This eliminates the need for the user to re-divide the cleaning areas and test the area dirtiness the next time they clean the cooking device. Instead, the user can directly determine the cleaning time and intensity for each cleaning area and proceed with cleaning the areas. This saves cleaning time, and when a historical cleaning pattern performs well, the user can continue to use it, eliminating the need for repeated adjustments and improving the user experience.

[0025] In a second aspect, an embodiment of the present application provides a cooking device, comprising: an inner pot, a heating cavity is formed inside the inner pot, and the heating cavity is used to hold food; a body, which constructs an outer shell for the cooking device and provides an installation space for the inner pot; a door body, rotatably connected to the body, and used to open or close the inner pot; a heating device, arranged in the body, and used to heat food; a cleaning device, arranged in the body, and used to clean the heating cavity; a turbidity sensing device, arranged in the body, and used to sense the liquid dirtiness value after cleaning the heating cavity; a controller, the controller being configured as: a testing unit, configured to control the cleaning device to perform test cleaning on the cleaning area in the heating cavity, and determine the regional dirtiness value of the cleaning area through the turbidity sensing device; a determination unit, configured to determine the cleaning mode of the cleaning area according to the regional dirtiness value of the cleaning area; and a cleaning unit, configured to perform formal cleaning on the cleaning area according to the cleaning mode of the cleaning area.

[0026] In an embodiment of the present application, a test cleaning of the cooking device is first performed, and the contamination value of the wastewater generated during the cleaning is obtained. The contamination value of the wastewater reflects the degree of contamination of the cleaning area in the cooking device. Therefore, the present application then determines a cleaning mode for the cleaning area in the heating chamber based on the contamination value of the wastewater. The cleaning mode includes cleaning time and cleaning intensity. The larger the contamination value, the longer the cleaning time and cleaning intensity. Finally, based on the determined cleaning mode, the cleaning area in the heating chamber is formally cleaned. This achieves the technical effect of automatically adapting the cleaning mode based on the degree of contamination of the heating chamber, achieving optimal cleaning efficiency and cleaning effect.

[0040] The present application provides a cooking device, comprising a body, an inner pot, a door, a heating device, a cleaning device, and a turbidity sensing device.

[0041] A heating chamber can be formed inside the inner pot. The heating chamber can be used to hold food. The machine body can be a shell for the cooking device. The machine body can provide installation space for the inner pot. The shell can be a rectangular hollow structure. The appearance shape of the machine body can adopt other shapes.

The heating device can be arranged on the inner pot. The heating device can heat food. The cleaning device can be arranged inside the heating chamber. The cleaning device can be used to clean the heating chamber. The turbidity sensing device can be arranged in the machine body. The turbidity sensing device can be used to sense the dirtiness value of the liquid after cleaning the heating chamber.

[0042] See also Figure 1 , Figure 1 The schematic diagram of the structure of a cooking device according to an embodiment of the present application is shown, which includes a body, an inner pot, a heating chamber, a door, a heating device (not shown in the figure), a clearing device, and a turbidity sensing device (not shown in the figure).

[0043] Based on the above cooking devices, such as Figure 2 As shown, Figure 2 A flow chart of a method for controlling a cooking device according to an embodiment of the present application is shown. The present application provides a method for controlling a cooking device, including the following steps:

[0044] Step S210, controlling the cleaning device to perform test cleaning on the cleaning area in the heating chamber, and determining the regional dirtiness value of the cleaning area through the turbidity sensing device;

[0045] Step S220, determining a cleaning mode for the cleaning area according to the regional dirtiness value of the cleaning area;

[0046] Step S230 , performing formal cleaning on the cleaning area according to the cleaning mode of the cleaning area.

[0047] The above three steps are described in detail below.

[0048] In step S210, before the cooking device is officially cleaned, a test clean can be performed on the cooking device to determine the degree of contamination of the cooking device. The specific degree of contamination can be represented by a regional contamination value of the cleaning area in the heating chamber. In other words, the contamination value of the wastewater generated during the test clean can be used to reflect the degree of contamination of the cleaning area.

[0049] See also Figure 3 , Figure 3 The flowchart of detecting the cleaning condition of the heating chamber according to one embodiment of the present application is shown. The embodiment of the present application provides steps for detecting the cleaning condition of the heating chamber, including:

[0050] Step S301, when sensing that the door is closed, responding to the user's instruction information to enter the cleaning mode;

[0051] Step S302, monitoring whether the heating chamber meets the cleaning conditions. If the heating chamber meets the cleaning conditions, controlling the heating device to start heating the heating chamber so that the heating chamber is heated at a constant temperature at the preheating temperature;

[0052] Step S303: If the heating chamber does not meet the cleaning condition, a prompt is given to the user that the heating chamber does not meet the cleaning condition.

[0053] The above three steps are described in detail below.

[0054] In step S301, considering that the heating chamber is being cleaned, the interior of the heating chamber must meet the cleaning conditions, such as the door is not closed, some components in the heating chamber need to be moved to the set position, and no food or some heating objects can be placed in the heating chamber to prevent affecting the spraying of liquid and the cleaning effect of the cleaning device.

[0055] When the cooking device responds to a user's instruction to enter cleaning mode, cleaning can only be performed when the door is closed. Therefore, when responding to a user's instruction to enter cleaning mode, it is necessary to check whether the door is closed. If the door is not closed, heating the heating chamber directly may pose a danger to the user. The cooking device can only enter cleaning mode in response to a user's instruction when the door is closed.

[0056] In step S302, upon entering cleaning mode, the heating chamber is first tested to see if it meets the cleaning conditions. Only when these conditions are met does the chamber begin to heat. The heating device is controlled to heat the chamber, maintaining a constant temperature at the preheating temperature to soften any dirt within. This facilitates subsequent test cleaning.

[0057] In step S303, when the heating cavity does not meet the cleaning conditions, the user is prompted that the heating cavity does not meet the cleaning conditions, prompting the user to check and clean the heating cavity to prevent safety accidents, which greatly improves the safety performance of the cooking device.

[0058] In this embodiment, the cleaning of the heating chamber requires that the interior of the chamber meet cleaning conditions. For example, if certain components within the chamber need to be moved to a predetermined position, and if food or other objects to be heated are still present within the chamber, these factors can affect the spraying of liquid by the cleaning device and the cleaning effect. Therefore, when the cooking device responds to user instructions and enters cleaning mode, it first monitors whether the chamber meets the cleaning conditions. Only when these conditions are met does it begin heating the chamber. If the chamber does not meet the cleaning conditions, the user is prompted to inspect and clean the chamber to prevent safety incidents and reduce cleaning effectiveness. Heating also softens stains, facilitating cleaning of the chamber.

[0059] See also Figure 4 , Figure 4 A flowchart of determining the contamination value of sewage using a turbidity sensing device according to one embodiment of the present application is shown. The turbidity sensing device includes a light source and a photosensitive device. The embodiment of the present application provides steps for determining the contamination value of sewage using the turbidity sensing device, including:

[0060] Step S401, causing the light source to emit a light beam, the light beam irradiating the sewage is sensed by the photosensitive device, and the sewage is generated by the test cleaning of the cleaning area;

[0061] Step S402, determining the contamination value of the sewage based on the brightness of the light beam sensed by the photosensitive device;

[0062] Step S403: determining the regional contamination value of the cleaning area according to the contamination value of the sewage.

[0063] The above three steps are described in detail below.

[0064] The turbidity sensing device may be disposed within the housing. The turbidity sensing device includes a light source and a photosensitive device. The light source is configured to emit a light beam toward the sewage. The photosensitive device is configured to sense the brightness of the light beam passing through the sewage. Specifically, the photosensitive device determines the brightness of the light beam passing through the sewage by sensing the change in brightness between the current and previous ambient conditions. The light beam does not necessarily impinge on the photosensitive device.

[0065] For example, the ambient brightness when the light source is not emitting a light beam is recorded as the default brightness. When the light source is emitting a light beam, the brightness sensed by the photosensitive device is the latest brightness. The difference between the latest brightness and the default brightness is the brightness of the light beam passing through the sewage as sensed by the photosensitive device.

[0066] In step S401, the light source is controlled to emit a light beam toward the sewage, so that the light beam is sensed by a photosensitive device through the sewage.

[0067] In one embodiment of the present application, the light source and the photosensitive device are movable. This allows the light beam emitted by the light source to illuminate the sewage at any location within the heating chamber. The movable photosensitive device also allows the photosensitive device to sense the light beam emitted from any location.

[0068] In one embodiment of the present application, the light source is rotatable. The photosensitive device is movable. The rotatable light source allows the light beam emitted by the light source to illuminate the sewage at any location within the heating chamber. The movable photosensitive device also allows the photosensitive device to sense the light beam emitted from any location.

[0069] In another embodiment of the present application, the light source is immovable. The photosensitive device is also immovable. The light beam emitted by the light source can illuminate the area where the sewage passes through the heating chamber. Alternatively, the light beam emitted by the light source can illuminate the area where the sewage is stored in the heating chamber. The photosensitive device senses changes in brightness between the current environment and the previous environment.

[0070] In step S402, the light beam emitted by the light source passes through the sewage and is sensed by the photosensitive device. If the photosensitive device detects a relatively high brightness of the light beam, this indicates that the light beam passed through the sewage without being reflected by many impurities before being sensed by the photosensitive device. This indicates that the sewage is relatively clean and does not contain many impurities, and the sewage pollution value is relatively low. If the photosensitive device detects a relatively low brightness of the light beam, this indicates that the light beam was reflected by many impurities in the light path before being sensed by the photosensitive device. This indicates that the sewage contains a large number of solid particles and impurities, and the sewage pollution value is relatively high. Based on the brightness of the light beam entering the sewage as sensed by the photosensitive device, the sewage pollution value corresponding to the perceived brightness is determined from a preset comparison table.

[0071] In step S403, the regional contamination value of each cleaning area is determined according to the contamination value of the wastewater generated during the test cleaning of the cleaning area in the heating chamber.

[0072] See also Figure 5 , Figure 5A flowchart is shown for controlling a cleaning device to perform a test clean on a cleaning area in a heating chamber and determining a regional dirtiness value of the cleaning area using a turbidity sensing device according to one embodiment of the present application. This embodiment of the present application provides a step S210 of controlling a cleaning device to perform a test clean on a cleaning area in a heating chamber and determining a regional dirtiness value of the cleaning area using a turbidity sensing device, including:

[0073] Step S501: test cleaning each cleaning area located on the inner wall of the heating chamber to obtain the contamination value of the sewage generated in each cleaning area;

[0074] Step S502 : determining the regional pollution value of each cleaning area according to the pollution value of the sewage generated in each cleaning area.

[0075] The above two steps are described in detail below.

[0076] In step S501, the inner wall of the heating chamber is the area to be cleaned, and the entire area to be cleaned is divided into several cleaning areas. Each cleaning area is tested and cleaned to determine the dirtiness value of the sewage generated in each cleaning area.

[0077] Step S502 : Determine the regional pollution value of each cleaning area based on the pollution value of the wastewater generated in each cleaning area. For example, the pollution value of the wastewater generated in each cleaning area is substituted into a preset formula to calculate the regional pollution value of the corresponding cleaning area.

[0078] It should be clear that when test cleaning is performed on each cleaning area, it can be done simultaneously or sequentially.

[0079] In the embodiment of the present application, each cleaning area located on the inner wall of the heating chamber is tested and cleaned separately to determine the regional dirtiness value of each area. In this way, the corresponding cleaning mode is determined based on the different dirtiness levels of each cleaning area, achieving more efficient cleaning and a higher degree of cleanliness.

[0080] See also Figure 6 , Figure 6 A flowchart of determining the regional contamination value of each cleaning area based on the contamination value of the wastewater generated in each cleaning area according to one embodiment of the present application is shown. The embodiment of the present application provides step S502 of determining the regional contamination value of each cleaning area based on the contamination value of the wastewater generated in each cleaning area, including:

[0081] Step S601: obtaining an initial dirtiness value of the sewage generated in the cleaning area through a turbidity sensing device at set intervals until the number of acquisitions reaches a set number;

[0082] Step S602 : taking the average of all initial dirtiness values ​​of each cleaning area as the dirtiness value corresponding to each cleaning area.

[0083] The above two steps are described in detail below.

[0084] In step S601, the wastewater obtained from the test cleaning of each cleaning area is tested using the turbidity sensing device at set intervals to determine its initial contamination value. This is repeated until the initial contamination value is obtained a set number of times. Since the set time is fixed, obtaining the initial contamination value for a cleaning area can be stopped once the test cleaning duration reaches the set time.

[0085] In step S602, all initial contamination values ​​of the cleaning area are summed and divided by the number of initial contamination values ​​to obtain the average of the initial contamination values ​​of the cleaning area, which serves as the regional contamination value of the cleaning area. The above-mentioned technical means are used to calculate the corresponding regional contamination value for each cleaning area to obtain the regional contamination value of each cleaning area.

[0086] It should be noted that when testing and cleaning each cleaning area at once, multiple light sources and corresponding photosensitive devices can be used to test the initial contamination value of the wastewater produced during the test cleaning of each cleaning area. Finally, the regional contamination value of each cleaning area is calculated.

[0087] In another embodiment of the present application, when test cleaning is performed on each cleaning area simultaneously, a single light source may be used. However, through means such as splitting, refraction, and reflection, multiple light beams can be emitted simultaneously to illuminate the wastewater generated during the test cleaning of each cleaning area. Corresponding light sensors are also provided, and the initial contamination value of the wastewater generated during the test cleaning of each cleaning area is determined based on the brightness of the light beam passing through the wastewater. Finally, the contamination value of each cleaning area is obtained.

[0088] In another embodiment of the present application, when cleaning each cleaning area one by one, only one light source is required to emit a light beam, and only one sensing device is required. Each time, only the initial dirtiness value of the sewage generated by testing one cleaning area needs to be obtained.

[0089] For example, the initial contamination value of the wastewater in the collection device is obtained at set intervals. After the test is completed, the wastewater in the collection device is pumped out to empty the wastewater. Then, the cleaning area is tested again, and the wastewater continues to flow into the collection device. The initial contamination value of the wastewater in the collection device is obtained again at set intervals. This continues until the number of initial contamination values ​​reaches the set number. The initial contamination value of the next cleaning area is then obtained.

[0090] In one embodiment of the present application, before test cleaning each cleaning area located on the inner wall of the heating chamber, the area to be cleaned located on the inner wall of the heating chamber is divided into several cleaning areas according to the user's instruction information, wherein the size and position of the cleaning area can be set according to the user's instruction information.

[0091] In an embodiment of the present application, based on the user's instruction information, the area to be cleaned on the inner wall of the heating chamber is divided into several cleaning areas, so that these divided cleaning areas can be cleaned in different cleaning modes. This can be cleaned separately according to the degree of dirtiness of the area to be cleaned on the inner wall of the heating chamber. Taking into full consideration the different degrees of dirtiness of different parts of the inner wall of the heating chamber, areas with similar degrees of dirtiness can be divided into the same cleaning area and cleaned in the same cleaning mode. This avoids the situation of incomplete cleaning or waste of resources. Because if all areas with different degrees of dirtiness are cleaned uniformly, if you want to clean them completely, you need to use the area with the most serious dirtiness as a reference for cleaning. This is completely unnecessary for areas with less serious dirtiness, which will waste resources. If you want to save resources, you use areas with general dirtiness as a reference for cleaning, which will result in incomplete cleaning of areas with serious dirtiness. Therefore, the present application divides the area to be cleaned into cleaning areas with different degrees of dirtiness, which not only improves cleaning efficiency but also saves resources.

[0092] In step S220, the degree of contamination of the cleaning area in the heating chamber can be determined based on the regional contamination value of the cleaning area. The degree of contamination can be represented by the regional contamination value. The degree of contamination of the heating chamber can be determined based on the obtained regional contamination value. A cleaning mode for the cleaning area in the heating chamber is then determined based on the regional contamination value corresponding to the cleaning area. The cleaning mode includes, but is not limited to, cleaning time and cleaning intensity. Cleaning intensity refers to the water pressure and water output during cleaning. A higher cleaning intensity results in a higher water pressure and a higher water output.

[0093] In one embodiment of the present application, a first cleaning mode comparison table is configured based on the regional dirtiness value of each cleaning area. In the first cleaning mode comparison table, different cleaning modes are associated with different regional dirtiness value intervals. The cleaning mode corresponding to a cleaning area is determined based on the numerical interval of the regional dirtiness value of the cleaning area. Each cleaning mode defines a cleaning time and cleaning intensity.

[0094] In one embodiment of the present application, if the total cleaning time is determined and all cleaning areas are cleaned simultaneously, the cleaning device can be provided with multiple nozzles to clean each cleaning area simultaneously. The total cleaning time is the cleaning time corresponding to each cleaning area. Based on the cleaning time corresponding to each cleaning area, the cleaning intensity corresponding to each cleaning area is determined. In the preset second cleaning mode comparison table, the corresponding cleaning intensity is searched based on the cleaning time and the area dirtiness value. The corresponding cleaning area is cleaned with this cleaning intensity.

[0095] See also Figure 7 , Figure 7 A flow chart of determining a cleaning mode for a cleaning area according to a regional dirtiness value of the cleaning area according to an embodiment of the present application is shown. The embodiment of the present application provides a step S220 of determining a cleaning mode for a cleaning area according to a regional dirtiness value of the cleaning area, including:

[0096] Step S701: If the total cleaning time is determined and each cleaning area is cleaned sequentially, the cleaning time of each cleaning area is determined according to the proportion of the dirtiness value of each cleaning area in the total dirtiness value of all cleaning areas;

[0097] Step S702 : determining the cleaning intensity according to the ratio of the regional dirtiness value of each cleaning area to the corresponding cleaning time.

[0098] The above two steps are described in detail below.

[0099] In step S701, if the total cleaning time is determined and each cleaning area is cleaned sequentially, a cleaning time must be allocated to each cleaning area. Specifically, the sum of the regional contamination values ​​of all cleaning areas is first calculated. Then, based on the ratio of each cleaning area's regional contamination value to the sum, the product of each cleaning area's ratio and the total cleaning time is calculated to obtain the cleaning time corresponding to each cleaning area.

[0100] In step S502, the cleaning intensity of each cleaning area is determined based on the ratio of the dirtiness value of each cleaning area to the cleaning time.

[0101] In an embodiment of the present application, when the total cleaning time is fixed and each cleaning area is cleaned sequentially, the sum of the dirtiness values ​​of all cleaning areas is first calculated. Then, based on the proportion of the regional dirtiness value of each cleaning area in the sum of the regional dirtiness values ​​of all cleaning areas, the amount of cleaning time that can be allocated to each cleaning area is determined. Finally, the cleaning intensity is determined based on the ratio of the regional dirtiness value to the cleaning time. The larger the ratio, the shorter the cleaning time is compared to the regional dirtiness value of the cleaning area, and a higher cleaning intensity is required to clean the cleaning area. This ensures that the cleaning effect of each cleaning area can be maintained as much as possible regardless of the cleaning time, and secondly, it saves cleaning resources.

[0102] In one embodiment of the present application, after determining the cleaning mode for a cleaning area based on the regional dirtiness value of the cleaning area, a historical cleaning mode is generated based on the division of the cleaning area, cleaning time, and cleaning intensity recorded in the cleaning mode. The distribution of previously cleaned areas, as well as the cleaning time and cleaning intensity of each cleaning area, are recorded to generate a previously used mode. This means that the next time the user cleans the cooking device, there is no need to redivide the cleaning area or test the regional dirtiness value. Instead, the user can directly determine each cleaning area and the cleaning time and cleaning intensity of each cleaning area, and clean each cleaning area directly. This saves cleaning time, and when a previously used mode has a good cleaning effect, it can be used continuously, avoiding the user having to debug over and over again, thereby improving the user experience.

[0103] In step S230 , a cleaning mode of the cleaning area is determined according to the regional dirtiness value, and the cleaning area is cleaned with the cleaning time and cleaning intensity defined by the cleaning mode.

[0104] In an embodiment of the present application, a test cleaning of the cooking device is first performed, and the contamination value of the wastewater generated during the cleaning is obtained. The contamination value of the wastewater reflects the degree of contamination of the cleaning area in the cooking device. Therefore, the present application then determines a cleaning mode for the cleaning area in the heating chamber based on the contamination value of the wastewater. The cleaning mode includes cleaning time and cleaning intensity. The larger the contamination value, the longer the cleaning time and cleaning intensity. Finally, based on the determined cleaning mode, the cleaning area in the heating chamber is formally cleaned. This achieves the technical effect of automatically adapting the cleaning mode based on the degree of contamination of the heating chamber, achieving optimal cleaning efficiency and cleaning effect.
